Role of Apolipoprotein E, Cathepsin D, and Brain-Derived Neurotrophic Factor in Parkinson's Disease: A Study from Eastern India.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Parkinson's disease (PD) is a progressive neurodegenerative disease with complex etiology. Both genetic and environmental factors play significant role. Apart from candidate genes, some modifier genes have been reported to be associated with the altered risk of PD. Previous studies have identified Apolipoprotein E (APOE), Cathepsin D (CTSD), and Brain-Derived Neurotrophic Factor (BDNF) as key players of neurodegenerative pathways with their variants associated with different neurodegenerative diseases. Hence, this study aims to identify the potential role of these modifier genes in the pathogenesis of PD among Eastern Indian PD patients. A case-control study was performed using 302 clinically diagnosed PD patients and 304 ethnically matched controls. Promoter SNPs of APOE (rs449647, rs405509) and BDNF (rs56164415), and coding SNPs of APOE (rs429358, rs7412 resulting in ε2, ε3, and ε4 alleles), CTSD (rs17571), and BDNF (rs6265) were analyzed by PCR-RFLP and bidirectional sequencing. The effect of rs56164415 on BDNF expression was characterized by Luciferase assay. APOEε4 allele was significantly overrepresented (p value = 0.0003) among PD patients, whereas ε3 allele was predominant in the control population. The promoter haplotype (A-rs449647, G-rs405509) of APOE was preponderant among female PD patients posing risk. No association was found for CTSD polymorphism. The 'T/T' genotype of BDNF rs56164415 was overrepresented (p-value = 0.02) among early onset PD patients. Expression of BDNF for the 'T/T' variant was significantly lower (p-value = 0.012) than the 'C/C' variant, suggesting a possible role in PD pathogenesis. This study suggests that APOE and BDNF may serve as modifier loci among eastern Indian PD patients.
